EPM7064SLC44-6

Complex Programmable Logic Devices Overview

The Altera EPM7064SLC44-6 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000S family. It features 64 macrocells, 1250 usable gates, and 36 user I/O pins housed in a 44-pin TQFP package. Operating at a maximum frequency of 175.4 MHz with a typical pin-to-pin delay of 5 ns, it supports 5.0-V in-system programmability via JTAG. The device utilizes CMOS EEPROM technology for non-volatile storage and includes enhanced features such as fast input registers and programmable output slew-rate control.

Complex Programmable Logic Devices Feature Summary

• In-system programmability (ISP) via IEEE Std. 1149.1 JTAG interface
• High-performance architecture with 5 ns pin-to-pin delays and 175.4 MHz counter speeds
• Enhanced logic resources including fast input registers and programmable slew-rate control
• EEPROM-based non-volatile memory allowing reprogramming up to 100 times

Complex Programmable Logic Devices Applications

• Data acquisition systems utilizing linear CCD sensors
• PCI-compliant digital logic interfacing
• Replacement for legacy PALs, GALs, and standard PLDs in mixed-voltage designs

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for end-of-life notifications, as this specific speed grade may have limited availability compared to current generations.

Complex Programmable Logic Devices Selection Notes

Select the -6 speed grade for designs requiring 5 ns propagation delay. Ensure the 44-pin TQFP package fits the PCB footprint. Verify that the design does not require MultiVolt I/O, as this feature is unavailable in 44-pin packages.

Complex Programmable Logic Devices Part Context

This part is part of the MAX 7000S series, which adds ISP capabilities to the MAX 7000E architecture. It shares architectural similarities with the EPM7064SLC44-10 but offers faster switching characteristics suitable for higher-speed synchronous applications.

Complex Programmable Logic Devices Replacement Considerations

Pin-compatible alternatives within the same package include the EPM7064SLC44-10 and EPM7064SLC44-7. For lower speed requirements, the EPM7064SLC44-12P is available.
